初のTOEIC公式単語帳のカバー率は? 公式ボキャブラリーブックを分析してみた

 


 

初の公式単語帳はどれくらいカバーできているのか?

TOEIC®L&Rテストで高得点を取るためには単語量を増やす必要があります。これまで、テストを運営している国際ビジネスコミュニケーション協会(以下IiBC)からは、公式問題集パート別のトレーニング本が販売されていましたが、2019年6月21日より初となる公式単語帳『TOEIC Listening & Reading 公式ボキャブラリーブック』の販売が始まりました。ここで気になるのが、公式単語帳からの出題率です。暗記分野なだけに、出題率が高い単語帳を選びたいところ。そこで、今回編集部では、公式単語帳から「どれくらいの割合で出題されるのか」を検証しました。

なお、TOEIC®テストの問題冊子を持ち帰ることはできないので、最新の傾向を反映してつつも本番に最も近い『公式TOEIC Listening & Reading 問題集5』(テスト2回分を収録)を元にリスニングとリーディングのパート別に単語の出題率を検証しました。

 
パート 索引数(index) 問題集5に出た単語数 単語出題率(%)
リスニングパート(TEST1) 1170 225 19.2%
リーディングパート(TEST1) 1170 450 38.4%
※上記表において、単語帳に収録されている単語数を「索引数(index)」、収録された単語の中から問題集5に出た単語を「問題集5に出た単語数」、「索引数(index)」から「問題集5に出た単語数」の割合を「単語出題率(%)」と表記。
※原形(go)・三人称(goes)・過去形(went)・過去分詞(gone)は1語とカウントしているが、形容詞(relative)や副詞(relatively)などの派生語は独立した単語として扱う(カッコ内は一例)。
